15 Claims. (01. 206-56) The invention relates to holder-containers for cosmetic crayons and other material of like manner of use, the object being the general improvement of such devices in respect of compact- 5 ness, ruggedness and appearance.

In the drawings which illustrate the preferred form of the invention,

Fig, l is a perspective elevation of the devi approximately life size; L Fig. 2 is a longitudinal section of line 11-11 of Figure I, greatly enlarged for sake of clarity;

Fig. 3 is a partial longitudinal sectional view at right angles to Figure 2;

Fig. 4, a section on IV-IV of Fig. 8; I Fig, 5, an elevation of the rotarysleeve;

Fig. 6, the fiat blank of which it can be formed; Fig. 7, an elevation of the main or outer cylinder;

Fig. 8, a partial cross-section showing the thumb piece and its keeper;

Fig. 9 a similar view of the inner cylinder.

The outside cylinder being in the present case the enamelled or ornamental casing of' the device is marked I and is ahollow cylinder which may be conveniently drawn out of brass stock. 25 It is provided with a longitudinal slot 2 for-a traveller button or thumb piece 3 which is retained 'in the slot by a small curved plate or keeper 4, see Fig. 8. When the cylinder is held in the fingers, the button 3 can be pushed back and forth with the thumb, being thus a one hand device. The casing is shown detached in Fig. '7. Next within the casing or main cylinder I is an inner rotary sleeve 5 connected to the button 35 3 by its spiral slot 6 so that the rectilinear mo'vemcnt of the button 3 rotates the sleeve relatively to and within the main cylinder I. Next within the rotary sleeve 5 is an inner cylinder I (Fig. 9) which is expanded at its 40 base and there secured in a permanent manner to the base endvoi the outer casing I. The junction of these two cylinders is covered over by a cap 8 which constitutes the bottom end closure and reinforcement of the device. It can be a pressed-fit thereon as indicated. The rotary sleeve 5 rotates in the annular space between the two united cylinders I and I and is retained against excessive endwise movement 50 therein by a stud 9 riveted in the inner cylinder I and engaging an arcuate slot III in the'lower part of the rotarysleeve 5. This rotary sleeve can be'made of a fiat sheet or blank, punched as shown in Figure 6 and rolled to the cylindrical 5 form indicated by Figure 5,'the meeting edges of the blank being locked together by the tongue and notch formation indicated by II and be- V tween them forming another spiral slot, presently referred to as the slot I6.

Next within the fixed sleeve I is the sliding 5 cup or carrier I2 which holds the crayon I3 in any suitable way as for example by friction, the crayon being merely pressed into the cup when the holder is open. The carrier is merely an open ended tube with one or more inbent tabs 10 I2 punched and bent out of its wall to form a seat for the crayon. It is provided with a stud I4 riveted thereto and adapted to ride in the longitudinal slot I5 formed in the inner fixed cylinder I and this stud I 4 projects through the 5 straight slot I5 into a second spiral slot I6, also formed in the rotary sleeve 5, this being the slot formed by the proximate edges of the rolled blank. The rotation of sleeve 5 moves the carrier up and down, the carrier being held against rotation by its stud engagement with the slot I5 of the relatively fixed cylinder 1. Preferably downward movement of the thumb piece 3 rotates the ,sleeve 5 in the direction to raise the can'ier toward the open end of the holder although this arrangement is not essential and could be reversed if desired and other forms of thumb-operated members could be provided for converting the thumb movement into rotary movement of the sleeve.

The closure mechanism of the holder is of the disappearing door type and comprises two quarter-spherical thin shelves or stampings I1 and I'l which are duplicates of each other and pivoted inside the holder to swing toward and from each other om a common transverse axis.

The end of the outer cylinder I is spherically tapered or inbent at its end to form a curved annular flange I which somewhat reduces thev diameter of the open end of the cylinder. The 40 two door members house under this fiange when opened, their paths of movement being close to and substantially concentric with the spherical taper. While the doon. members may be otherwise mounted and otherwise operated, it is preferred to pivot their hub portions on the two upstanding posts I8 which rise from the upper end 0! the inner cylinder I and these pivots are conveniently formed as e elets I9 integrally stamped or drawn out of the material of the posts I8 themselves. Each door member hub is cut or stamped with a pair of gear teeth marked 20 and 20' respectively and these teeth directly overlie the top edge of the rotary sleeve 5 and are arranged to be engaged by corresponding 5 teeth 2i and 2| cut in such top edge, there being two teeth 2! on one side of the sleeve, and two, 2|, on the other. The doorsand their teeth are punched out of relatively thin sheet stock and the combined thickness of their hubs 15811011; equal to that of the sleeve. The teeth are arranged in such manner that rotation of the sleeve swings the two members toward orfrom each other, closing them together on the center line of the device, and opening them to positions under the flange, i. The doors are opened by the initial movement of the sleeve 5 after which one of the teeth on each door member rides along on the smooth top edge of the sleeve, thus holding the member open. on return of the sleeve to itsinitial position, the door teeth are picked upagain by the sleeve teeth and thereby restored .to closed position.v

This action is timed so that the doors are open at the proper point to permit the crayon to protrude and are closed after it has receded through the door opening-r- 1 While it is desirable that the door segments shall operate close to the inner face of the spherical flange I thus to make a tight dustexcluding closure, it is also important that they shall not rub or bind thereon at least to such an extent as to interfere with their free action and make the device diflicult to operate. Such binding eflect unless prevented is likely to oc-' cur from distortion, under the pressure of the user's thumb of the casing I. This as well as the other cylinders are made of the thinnest practical section for the sake of lightness of weight, and economy of material, the rotary sleeve being the thickest member on account of its teeth and the work it has to perform. Such distortionflis guarded against according to this invention, in part by the spherical taper or flange i; which stiifens the casing l and in part by giving such casing .one or more points of internal support. Three of such supports are represented by. the pimples 22, which are punched in the rotary sleeve 5 and two other points may be provided by allowing contact of the casing upon the upset ends of the pivot eyelets IS on the posts II.. The base end of the casing l is stifi'ned by the inner cylinder as well as by the cap 8. In thiswaya very light outer casing, of uniform-diameter from end to end, may be employed and even though slotted for nearly its full length without danger of such distortion as would impose an excessive friction either on the door members or on the keeper l of the sliding thumb piece, which latter mustv slide freely at all times in the annular crevice between the outer cylinder and the rotary scribed is intended.
